Definitions
- This invention relates to a container for receiving a food product and in particular the invention is concerned with containers that can be formed by folding a shaped blank of paper, paperboard, cardboard or a similar material.
- a first aspect of the present invention provides a partially assembled container as defined in the appended claim 1.
- This novel container construction provides a partially formed container that has a number of advantages over known constructions such as, for example, those disclosed in GB 2398557 and GB 2321236 .
- it can be moved quickly and easily between a flat configuration to an erect configuration without the need for tabs or tongues to be inserted in pre-cut slots or additional gluing.
- the container "pops up" from the flat configuration to the erect configuration when the sides of the flat container are pulled apart.
- the partially formed container makes very efficient use of the blank material, thereby decreasing costs. Further, the partially formed container can be transported in the flat condition, and then erected easily by the food producer.
- first hinge part is hingedly connected to said one side wall
- second hinge part is rigidly connected to said one end wall.
- the first and second hinge parts lie in substantially the same plane when the container is in a substantially flat condition, and the first hinge part and said one end wall sandwich the second hinge part when the container is in a substantially erect condition.
- the hinge means additionally comprises a third hinge part hingedly connected to the second hinge part and rigidly connected to the said end wall.
- the third hinge part is hingedly connected to the second hinge part and rigidly connected to the said end wall such that the said end wall is sandwiched by the second and third hinge parts.
- the third hinge part is hingedly connected to the second hinge part and rigidly connected to the said end wall such that the said third hinge part is sandwiched by the end wall and the second hinge part.
- the third hinge part is hingedly connected to the second hinge part and rigidly connected to the said end wall, and the first hinge part is securely fastened to one of said triangular side walls when the container is in its substantially erect position provision.
- the provision of the third hinge part complicates the construction of the container slightly, but its provision is advantageous because it improves the integrity of the seal between the second hinge part and the said end wall to improve the shelf life of the food product contained in the finished container.
- the third hinge part and the surface of the end wall to which it is connected may substantially congruent so that the third hinge part of the hinge means and the said end wall provide a basal surface for the container with double thickness.
- This double thickness basal surface helps to prevent or delay leakage for the contents of the food product from the container.
- the hinge means are preferably integral with the said side wall. This feature simplifies the blank from which the partially formed container is constructed, and it helps to improve the integrity of the finished container.
- the partially assembled container according to the first and second preferable alternatives is particularly suited to a relatively automated process where the container is opened by machinery provided for that purpose such that a food product can then be inserted manually or by further machinery, and this development is realised by adopting a two stage construction process in which:
- the partially fastened container described in step (1) is suitable for transportation and storage prior to use.
- the partially fastened container can be folded quickly and easily by apparatus provided for that purpose and then the container can be secured in its erect condition ready for receipt of a food product by fastening the first and second hinge parts as described in step (iii).
- the configuration of the partially formed container allows steps (ii) and (iii) to be accomplished at high production speeds on known forms of folding and fastening apparatus, or apparatus of that type with simple and inexpensive modifications. These benefits are achieved because the partially fastened container lies flat, making it easier for the machinery to pick and denest it.
- the third hinge part is secured to the inner face of the end wall, such that the end wall and the first hinge part sandwich the second and third hinge parts.
- the sandwich pack provides four blank external faces and this simplifies printing onto those external surfaces with advertising, nutritional information or other matter.
- a container to be formed from a blank with very minimal scoring of the joints to provide a good shelf life performance, and also enable the partially assembled container to be made up easily into a flat configuration for transportation and storage and opened equally easily into an erect configuration for insertion of a food product.
- the preferred three part hinge arrangement provides an excellent seal and extended shelf life for the food product, but a two part hinge arrangement would also be possible and might be used where the shelf life of the food product is not a crucial factor.
- the present invention also provides a blank for forming a container for receiving a food product, the blank having triangular side walls and substantially rectangular end walls to enable the formation a generally triangular prism-shaped container with an opening for receiving the food product, the blank further comprising hinge means, the hinge means comprising a first hinge part hingedly connected to a second hinge part and arranged between one of said side walls and one of said end walls to enable a partially assembled container formed from the blank to be moved between a substantially flat position for storage and transportation and a substantially erect position for receiving a food product.
- the container blank or skillet shown in Figure 1 may consist of paper, paperboard, cardboard or a similar material.
- a pair of congruent isosceles-shaped side walls 2a and 2b are alternately arranged with and hingedly connected to generally rectangular end walls 3a and 3b.
- the end walls may be rectangular, but they are preferably trapezoidal so that in the fully assembled container they taper inwardly towards an apex to allow a number of assembled containers to be stacked together.
- the end walls have opposed major and minor edges, designated 4a and 4b respectively. Both of the major edges 4a of the end walls 3a are flanked by the congruent edges of the side walls 2a and 2b. Side wall 3b has one of its major edges 4a integrally formed with a congruent edge of side wall 2b.
- a hinge arrangement integrally formed with side wall 2a has three parts: generally rhombic flap or tab 5; a triangular central part or panel 6; and a three sided part or panel 7. These three parts are integrally formed and connected by fold lines. Panel 7 is integrally formed with side wall 2a.
- the flap 5 is hingedly connected to the minor edge 4a of end wall 3a and this hinge point forms the apex of the finished triangular prism-shaped container.
- the hinge arrangement 5,6,7 is folded to overlie the side and end walls 2a, 3a.
- End wall 3b is then brought into abutment with the exposed surfaces of the flap 5 by folding the side wall 2b about its central fold line as shown in Figure 3 .
- the abutting surfaces of the flap 5 and the end wall 3b, both designated as S1 in Figure 2 are glued together to form a permanent join.
- These surfaces S1 are substantially (but not completely) congruent to form a double thickness wall.

Abstract
Description
- This invention relates to a container for receiving a food product and in particular the invention is concerned with containers that can be formed by folding a shaped blank of paper, paperboard, cardboard or a similar material.
- A first aspect of the present invention provides a partially assembled container as defined in the appended
claim 1. - This novel container construction provides a partially formed container that has a number of advantages over known constructions such as, for example, those disclosed in
GB 2398557 GB 2321236 - In one embodiment the first hinge part is hingedly connected to said one side wall, and the second hinge part is rigidly connected to said one end wall. The first and second hinge parts lie in substantially the same plane when the container is in a substantially flat condition, and the first hinge part and said one end wall sandwich the second hinge part when the container is in a substantially erect condition.
- In another embodiment the hinge means additionally comprises a third hinge part hingedly connected to the second hinge part and rigidly connected to the said end wall. Preferably, the third hinge part is hingedly connected to the second hinge part and rigidly connected to the said end wall such that the said end wall is sandwiched by the second and third hinge parts. In a first preferable alternative, the third hinge part is hingedly connected to the second hinge part and rigidly connected to the said end wall such that the said third hinge part is sandwiched by the end wall and the second hinge part. In a second preferable alternative, the third hinge part is hingedly connected to the second hinge part and rigidly connected to the said end wall, and the first hinge part is securely fastened to one of said triangular side walls when the container is in its substantially erect position provision.
- The provision of the third hinge part complicates the construction of the container slightly, but its provision is advantageous because it improves the integrity of the seal between the second hinge part and the said end wall to improve the shelf life of the food product contained in the finished container.
- The third hinge part and the surface of the end wall to which it is connected may substantially congruent so that the third hinge part of the hinge means and the said end wall provide a basal surface for the container with double thickness. This double thickness basal surface helps to prevent or delay leakage for the contents of the food product from the container.
- The hinge means are preferably integral with the said side wall. This feature simplifies the blank from which the partially formed container is constructed, and it helps to improve the integrity of the finished container.
- The partially assembled container according to the first and second preferable alternatives is particularly suited to a relatively automated process where the container is opened by machinery provided for that purpose such that a food product can then be inserted manually or by further machinery, and this development is realised by adopting a two stage construction process in which:
- 1) the third hinge part is fastened to the said end wall and the partially fastened container is folded into a substantially flat configuration;
- 2) the partially fastened container is stored and transported to a food producer or user;
- 3) the partially fastened container is opened; and
- 4) the container is erected by bringing the hinge parts into abutment, or by securing the first hinge part to one of the triangular side walls and then securing the hinge parts in the abutting configuration.
- The partially fastened container described in step (1) is suitable for transportation and storage prior to use. The partially fastened container can be folded quickly and easily by apparatus provided for that purpose and then the container can be secured in its erect condition ready for receipt of a food product by fastening the first and second hinge parts as described in step (iii). The configuration of the partially formed container allows steps (ii) and (iii) to be accomplished at high production speeds on known forms of folding and fastening apparatus, or apparatus of that type with simple and inexpensive modifications. These benefits are achieved because the partially fastened container lies flat, making it easier for the machinery to pick and denest it.
- It is preferred in the first preferable alternative that the third hinge part is secured to the inner face of the end wall, such that the end wall and the first hinge part sandwich the second and third hinge parts. In this configuration the sandwich pack provides four blank external faces and this simplifies printing onto those external surfaces with advertising, nutritional information or other matter.
- Overall the combination of these features allow a container to be formed from a blank with very minimal scoring of the joints to provide a good shelf life performance, and also enable the partially assembled container to be made up easily into a flat configuration for transportation and storage and opened equally easily into an erect configuration for insertion of a food product. The preferred three part hinge arrangement provides an excellent seal and extended shelf life for the food product, but a two part hinge arrangement would also be possible and might be used where the shelf life of the food product is not a crucial factor.
- The present invention also provides a blank for forming a container for receiving a food product, the blank having triangular side walls and substantially rectangular end walls to enable the formation a generally triangular prism-shaped container with an opening for receiving the food product, the blank further comprising hinge means, the hinge means comprising a first hinge part hingedly connected to a second hinge part and arranged between one of said side walls and one of said end walls to enable a partially assembled container formed from the blank to be moved between a substantially flat position for storage and transportation and a substantially erect position for receiving a food product.

Figure 17 is a perspective view of a partially assembled container in an erect configuration; -
Figure 18 is a plan view of a container according to a fourth embodiment; -
Figures 19 ,20 and21 are views of the blank shown inFigure 18 in an intermediate stage of construction; and -
Figure 22 is a perspective view of a partially assembled container in an erect configuration. - The container blank or skillet shown in
Figure 1 , and generally designated 1, may consist of paper, paperboard, cardboard or a similar material. A pair of congruent isosceles-shaped side walls rectangular end walls - The end walls have opposed major and minor edges, designated 4a and 4b respectively. Both of the
major edges 4a of theend walls 3a are flanked by the congruent edges of theside walls Side wall 3b has one of itsmajor edges 4a integrally formed with a congruent edge ofside wall 2b. - A hinge arrangement integrally formed with
side wall 2a has three parts: generally rhombic flap ortab 5; a triangular central part orpanel 6; and a three sided part orpanel 7. These three parts are integrally formed and connected by fold lines.Panel 7 is integrally formed withside wall 2a. Theflap 5 is hingedly connected to theminor edge 4a ofend wall 3a and this hinge point forms the apex of the finished triangular prism-shaped container. - All of the connecting lines shown in
Figure 1 represent valley or hill folds with valley folds shown with icon A and hill folds shown with icon B. Icon C shown betweenflap 5 andend wall 3a represent a cut line. - Oral flaps or
tabs 8a to 8e formed withside walls 2, the end walls and thepanel 7 cooperate in the assembled container to define a flange which is surrounds themouth 9 of the container. - Turning now to
Figure 2 , thehinge arrangement end walls End wall 3b is then brought into abutment with the exposed surfaces of theflap 5 by folding theside wall 2b about its central fold line as shown inFigure 3 . The abutting surfaces of theflap 5 and theend wall 3b, both designated as S1 inFigure 2 , are glued together to form a permanent join. These surfaces S1 are substantially (but not completely) congruent to form a double thickness wall. This double thickness wall can be used as the base on the finished container to provide addition resistance against the egress of the food product housed within the container. - As shown in
Figure 3 , the blank is further folded about the join between thetab 5 and thecentral panel 6 to bring part of theend wall 3b into abutment with the exposed surface of thecentral panel 6. The abutting surfaces of thefirst element 6 and theend wall 3b, both designated as S2 inFigure 3 , are glued together to form a permanent join and thereby sandwich part of theend wall 3b between theflap 5 and thecentral panel 6. The resultant partially formed container is shown inFigure 4 , and this configuration represents the partially formed container in its flat configuration. - The configuration of the container means that when it is opened by, say, pulling the
side walls Figure 4 and the erect configuration shown inFigure 7 is depicted, as far as it is possible to do so, inFigures 5 and6 . - In the erect configuration the
panel 7 and theend wall 3b sandwich thecentral panel 6, and the container can be fixed in a fully formed configuration by permanently joining the abutting parts of thesepanels panel 7 will abut the part of theend wall 3b and the container can be fixed in a fully formed condition by joining these abutting surfaces. In an alternative embodiment a catch or detent mechanism can be provided so that the partially assembled container can be mechanically fastened in an erect condition without the use of glue or other permanent fastening. - The
oral flanges - The preferred embodiment of the invention, which is depicted in
Figures 1 to 9 and described above, has a hinge arrangement made up from three parts. However, it will be apparent to a person skilled in the art that a two piece hinge arrangement made up from thepanel 7 and thecentral panel 6 would function in the same manner. The use of theflap 5 is advantageous because it improves the integrity of the seal between the hinge arrangement and theend wall 3b, and it also provides a double thickness basal surface in the finished container, but if the shelf life of the food product does not need to be maximised then theflap 5 could be omitted to reduce the amount of material used in the blank. - In the second embodiment shown in
Figures 10 ,11 and 12 , andintegral lid 10 is provided in place of theoral flap 8dadjacent side wall 2a. The lid is used to close theopening 9 in the finished container after the food product has been inserted. Thelid 10 has anopening 11 which is covered by atransparent film 12 to enable the contents of the assembled container to be viewed after the peripheral end of the lid is sealed to the oral flange 8. The blank and container configuration allow the lid to be provided without a fold lines passing through the lid. - In the third and fourth embodiments shown in
Figures 13 to 22 , like parts are numbered in the same sequence as the first end second embodiments, but the sequencing starts at 100 rather than at 1 in the third embodiment, and 200 in the fourth embodiment. - It should be noted that, in contrast to the first and second embodiments, the fold line between the triangular central part or panel (106, 206) and the three sided part or panel (107, 207) in the third and fourth embodiments is a hill fold. This enables the hinge arrangement to be located internally in the erect container, and this modification could be applied to the first and second embodiments.
- The construction of the third and fourth embodiments of the container involve the same steps, but the containers of these developments are particularly suited to a "pick and place" arrangement where the container is stored and shipped in a flat pack form, and then the construction finished at the site of the food producer by opening the container and securing the hinge arrangement. This second stage in the construction process of opening the container from a substantially flat condition and securing the hinge parts in secure abutment is well suited to automation. The hinge parts can be secured by an appropriate means such as gluing, heat sealing or RF welding.
- A food product such as a sandwich can then be placed in the erected container by hand or by apparatus designed for that purpose, and the opening to the container closed and seal with a lid or suitable covering.
- In the third embodiment, the hinge parts and the end wall provide a quadruple layer of paperboard, and this can be used as the base of the container to stop or slow down the egress of any moisture or liquid that might be contained in the sandwich.
Also the construction of this development allows the hinge parts to lie within the container leaving four blank panels on which marketing information can be placed. - In the fourth embodiment, the hinge parts also lie within the container leaving four blank panels on which marketing information can be placed.
- The invention is not restricted to the embodiments of the invention explicitly described herein, and modifications within the scope of the invention described in the claims will be apparent to the person skilled in the art. For example, references to sections of the blank being glued should be understood to encompass any form of fastening including RF welded by application of a suitable coating to the surfaces that are being joined.
